is'swung to one side.

, from the furnace.

.so that said 'water connections will not be disturbed Vwhen the burner is swung away Said pipe connections enter the Water chamberS of the side wall 7, as

at 32, and said water chamber is connected to the opposite water chamber 8A of the wall 6 through a horizontal pipe connection 33`adjacent the front portion of the walls andnear the bottom thereof. -m

The water chamber 8 of the wall 6.is com municatively connected with the water chamconnections `35.` Extending out of said water chamber 16` is a Vpipe 36 directed horizontally andfthence upwardly, as at 37, and including a swivel joint fitting 38 in axial alignment lwith thehingepinsQ and the swivelfitting "-This a lwater circulation is` established throughthe water chambersS and 16 which maybe utlizedforthe provision'of a hoty `water `supply for domestic purposes and iat thesame time affordinga cooling system to. maintain the temperature of the walls surrounding the combustion ychamber at: a degree which will prevent their rapid deterioration.

\ The pivotal joints `afforded by the'hinge pins 26 ,and the :swivelttings 31 and 38 insure l that thewater connections "will not be dislilrted upon burner.

The'gratestructureof myk invention consists in` a removable frame comprising side plates. 40 adjacenttheoppositewalls 6 and Z of the burner. Y Grate bars 41M are pivotally v connected at 42 in ,saidplates andare each provided withalug 43 `having pivot pins 45 ,entered selectively in eitherv of a pair of holes 46 in atie bar 47 to give saidgrate Vbars either of two selected inclinations, respectively.- Saidtie bar is controlled by Vmeans of a rack' bar 48 extending through the door 11 and maintainedin adjusted position by meansof apivoted dog 50. Y

The grate bars v53 are j `further provided with lugs 57 pvotallycon nected to abarV 58which is controlledV by a rod @extending tothe dooi1 11. Y S

The kgrate bars may be f `lf`i7henthrust forwardly, as vindicated in brokenlnes in Fig. 2, the plate 51 will swing forwardly therewith and partially block said throat opening, whereupon the sawdust or other fuel will be partially blocked in its dev scent and thesupplyiof'fuel will be retarded. ber 16 of the top plate 15 by means ofpipe a-supply offhot water fordomestic purposes.

or which maybe in a steam or hot water boiler connected with theY hot water o f the furnace V gives a valuable adjunctlto ythe invention.

The provision of means for swinging the entire structure to admit of access to the furnace for cleaning or repairs isa still further ad--V vantage in my new construction.

f From the foregoing construction, taken in connection with the accompanying, drawings, the advantages of the construction and application .j of my improved ,water cooled' comminuted fuel burners willbe readily ap! parent glbut, while I have described the principle ofoperationofthe invention, together' with .the structures which I now consider the best embodiment thereof, it' will be readily understoodv that the devices shown are merely illustrative andthat suchchanges may be inade therein' as will lie within* the Vscope of the following claims. j Having described my claim, is: j f A A burner for furnaces, consisting in a b ase, walls movably supported onsaid base, a throat element superimposed on said side walls ,connecting them together, a hopper mounted on said throat element, a platerigidf ly connected to said sidewalls 'rearwardly of said throat element, saidl side walls and said plate being chambered toy providewater pas# sages, water communicating -connections between s'aid water passages, meansto'hingedly connect said burner to afurnace, pipe con-V nect-ions to supply water and withdraw thel same -Afrom said passages, andswivel l.devices in said pipe connections in axial alignment with the hinge connections of the burner;

j 2. A burner for furnaces, consisting in a fire-box pivotally mounted toswing in horiinvention, what I zontal directions, the side Walls and top of said irebox being separably connected together and each formed With a Water-chamber, Water supply and discharge pipes communieating with said chambers respectively provided vvth swivel-joints inthe axis of pivotal movement of the {ire-box, and pipe connections between the side Wall chambers and between one of said side Wall chambers o and the chamber of the top Wall.
